 **OPNSense firewall - Basic configuration**
+====== allowing ICMP on your WAN interface? ======
+  I had problems when trying PING to the firewall....When I started the firewall,  for a few moments the PING
+  worked and then few seconds after it stops to respond. From inside the OpnSense I could PING my Desktop but from
+  my Desktop can not PING the Firewall..
+  My default "Default allow LAN to any rule" was disable because I want to control all the traffic that cames from
+  my LAN to my WAN.
+  So, I had  to create a specific rule to allow ICMP traffic:
+  Action: Pass
+  Interface: LAN
+  Protocol: ICMP
+  ICMP type: Echo Request
+  Source: LAN net
+  Destination: This Firewall
+  description: Allow Ping
+  After this ( and this is important ) I need to run "States reset"  ( Firewall->Diagnostics->Stated Reset ) to
+  finally get the correct response of the PING to my Desktop.
